NC/GAP-TPE共混聚合物的制备和性能研究
Preparation and characterization of polymer blends of NC and GAP-TPE
摘要
Abstract
A series of blends of energetic thermoplastic polyurethane( GAP-TPE)and Nitrocellulose( NC) were prepared by the way of chain extension,blend and aging. The structures of the blends were analyzed by means of FT1R spectroscopy, wide-angle Xray diffraction,and scanning electron microscopy. The compatibility and properties of the blends were characterized by dynamic mechanical analysis( DMA)and tensile testing. It suggests that nitrocellulose molecules penetrate into the polyurethane and interrupt the intra-hydrogen bonding between the hard and soft segments. The results indicate that the blended sheets exhibited good miscibility. The tensile strength increased with an increase of NC content. The blends NC/GAP-TPE having 5%～20% NC exhibited a significant increase from 10.4 Mpa to 20.4 Mpa for tensile strength ,49% increased.关键词
